Inspirational A critically acclaimed #1 New York Times bestseller with more than one million copies in print and a major motion picture! Gritty with pain, betrayal, and brutality, this incredible true story also shines with an unexpected, life-changing love. Meet Denver, raised under plantation-style slavery in Louisiana until he escaped the "Man" in the 1960's by hopping a train. Untrusting, uneducated, and violent, he spends 18 years on the streets of Dallas and Fort Worth. Meet Ron Hall, a self-made millionaire in the world of high-priced deals—an international arts dealer who moves between upscale New York galleries and celebrities. It seems unlikely that these two men would meet under normal circumstances, but when Deborah Hall, Ron's wife, meets Denver, she sees him through God's eyes of compassion. When Deborah is diagnosed with cancer, she charges Ron with the mission of helping Denver. From this request, an extraordinary friendship forms between Denver and Ron, changing them both forever. A tale told in two unique voices, Same Kind of Different as Me weaves two completely different life experiences into one common journey. There is pain and laughter, doubt and tears, and in the end a triumphal story that readers will never forget. Bonus material in this special movie edition includes: A new epilogue with updates on the authors since the release of the original book The amazing story behind the movie, how it got made, and the incredible experiences while filming in Jackson, MS |
